IMPROVEMENT iN -SULKVCUI TlhlOPS.A

Specification forming part of Letters Patent No. 120,435, dated October31, 1571.

To all whom t may concern.-

Be it known that I, PHILIP HEWITT, of Farmland, in the county ofRandolph and State of Indiana, have invented a new and usefulImprovement in Sulky-Cultivator, and I do hereby declare that thefollowing is a iiill, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing had to the accompanying drawing forming part of thisspecifica-tion.

Figure l is a top view of my improved machine, the cover being removed.Fig. 2 is a detail vertical longitudinal section ofthe saine takenthrough the line w m, Fig. l.

My invention has for its object to furnish an improved sulky-cultivator,strong, durable, simple in construction, convenient in use, andeffective in operation; and it consists in the construetion andcombination of various parts of the machine, as hereinafter more fullydescribed.

A are the sulky-wheels, which revolve upon the short axles B. Upon theinner ends of the axles B are formed cross-bars C, which extend alongthe under sides ofthe side-bars ofthe frame D, to' which th ey aresecured by clips E, as shown in Figs. l and 2, so that the said axlescan be conveniently moved forward or backward, to enable the machine tobe accurately balanced. D is the frame, the front and rear cross-bars ofwhich are each bent four times at right angles or into U-shape to forman offset or space to enable the machine to pass over tall corn withoutbreaking' or injuring it. To the upper horizontal part of the frontcross-bar of the frame D is attached the rear end of the tongue G, whichis further supported and strengthened by the curved cross-bar H, the endparts of which are bent downward and securely bolted to the frontcorners of the frame D. I are the plow-beams, which are made in pairs,the forward ends of each pair being formed solid with, or rigidlyattached to, each other. The forward end of each pair of beams I ispivoted to ahorizontal plate, J, several holes being formed in the saidplate to receive the pivoting bolt, so that the rear parts of the beamsI may have a free lateral movement. The plates J are secured to thefront horizontal parts of the frame D by clips, as shown in Figs. l and2,v so that the said plates J may rack, to give a free vertical movementto the rear ends of the plowbeams. The rear parts of the beams of eachpair incline from each other, and are held in their proper relativeposition by tubular washers or blocks K placed upon the arms ofthestaples L, which pass through said beams and are secured in place bynuts screwed upon their ends. The beams I of each pair are iliade ofunequal length, and the rear ends of all the beams are curved downward,as shown in Fig. 2. To the rear end of each oi" the beams I is pivoted ashoe, M, which is curved to correspond with the curvature of the rearends of the said beams I. The lower ends of the shoes M are made solid',to form a seat for the plows N, and Ytheir middle and upper parts aredeeply grooved upon their rear sides to receive and fit upon the rearparts of the beams I, said groove being extended entirely through in themiddle parts of the said shoe M to allow the shoe M to turn back, assh'own in Fig. 2. Through the upper part of the shoe M, and through thebeam I, is formed a hole, in which is inserted a wooden pin, O, whichshould be made of such strength as to support the draft strain upon theshoe M, under ordinary circumstances, but should be suficieutly weak tobreak, should the plow strike an obstruction, before any other part ofthe machine may break, thus preserving the machine from injuriousbreakages. To the inner side of the inner beam I of eachl pair isattached a footrest, I), to receive the drivers feet, so that he mayguide the plows-with his feet when desired. To the outer flange of thefoot-rests P are bolted the upper parts of the plates Q, which haveslots formed in them to receive the said bolts, so that the said platesQ, can be conveniently raised and lowered, as required. To the lowerends of the plates Q, are attached wires or rods It, coiled intoelongated or flattened spirals, and which serve as fenders to preventthe clods thrown up by the plows from being thrown against the plantsand covering, breaking, or injuring them. To the sidev bars of the frameD, nearly over the axles B, a-re bolted the ends of the bar or narrowplate S, which is bent and curved, as shown in Fig. l and 2, and to theforward or central horizontal part of which may be attached a box, T,for containing the tools that may be necessary to use in adjustin g themachine. U are levers, the lower ends of which are pivoted to the beamsI by means of the staples L, or other convenient means. The levers Uproject through slots in the bar or plate S, which thus serves as afulcrum to said levers.

The upper ends of the levers U project into such the bar or plate S. Therear ends of the levers- V project up into such a position that they canbe conveniently reached and operated by the driver from his seat toraise the plows from the ground for convenience in turning or passingfrom place to place. To the forward ends of the levers V are attachedpins fv, to receive a link of the chain W, the end of which is attachedto a beam, I, so that by adjusting the length of the chains W the plowsmay be raised to a greater or less distance from the ground, as may berequired. X are catches, which are attached to the rear parts of the baror plate S in such positions as to receive the rear parts of the leversV, When depressed, to raise the ploWs, and thus hold the plows raisedfrom the ground. Y is a Wire or rod, the ends of which are inserted inkeepers or sockets attached' to4 the forward vertical parts of the plateor bar S. After the rods Y have extended up to a convenient height theyare bent to the rearward to form a frame to receive canvas or othersuitable material to form a cover for the drivers seat.

Having thus described my invention, I claim as newr and desire to secureby Letters Patent- 1. Fenders, formed of spiral-Wire coils R, andattached to plates Q, on the inside of the cultivator ploWs, as and forthe purpose speciiied.

' 2. The combination of frame S provided with levers V V and havingslots thereon, the beams I I provided with levers U U passing throughsaid slots, and the frame D having seat F on the rear thereof, allconstructed and arranged as and for the purpose specified.

PHILIP HEWIT'I.
